WHEEL.

Application filed December 1, 1924.

Wheels, of which the following is a full,

clear, and exact description.

My invention relates to improvements in wheels, and it consists in thecombinations, constructions, and arrangements herein de scribed andclaimed.

An object of my invention is to provide an improvement over that form ofthe device shown in my co-pending application for wheel, Serial No.232,835, filed August 18,

1924:. In said" co-pending application I showed a device in which therim could be positively moved into locking engagement with the felly ofthe wheel, and positively loosened from the felly, these two operationsbeing accomplished by a single bolt. I further showed novel means forwedging the rim to the felly at various places, whereby the felly couldbe readily secured to the rim.

' ihe principal object of the present application is to construct themeans for securing the rim to the felly in such a manner that the rim,although rigidly secured to the device, will not be so fastened to thefelly that it cannot be readily released from the felly.

A further object of my invention is to provide a wheel in which thefelly has novel means for engaging with both sides of the rim so as toprovide a large supporting surface for the rim. 7

A further object of my inventionis to pro vide a wheel which isextremely simple in construction, positive in operation, andwhich isdurable and etlicient for the purpose intended. V

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawings, forming partof this application, in which Figure 1 is a plan view of a portion ofthe felly,

Figure 2 is aside elevation or Figure 1,

Serial No. 753,282.

Figure 3 is a section substantially alongthe line 33 of Figure 2,

Figure 4 is a plan View of another portion of the felly,

Figure 5 is a side elevation of Figure 4, Figure 6 is a section alongthe line 66 of Figure 5, and

Figure 7 is a section through a modified form of the device.

In carrying out my invention I provide a felly which in the presentinstance is con structed of metal and which is provided.

with a cylindrical portion 1, (see Figure 6) and outwardly extendingflanges 2 and 3. The felly is mounted upon spokes 1 and is provided withopenings 5 in which the free ends of the spokes 4 are received. It willbe noted, from Figures 1 and 6 that the flanges 2 and 3 are bentinwardly at 6 and 7 so as to provide inclined surfaces for a purposehereinafter described. It willalso be noted that the sides 2 and 3 andthe inclined surfaces 6 and 7 act as reenforcing means for the felly.

The means for locking the rim 8 to the felly consists in a locking plate9 and looking projections 10. I have found that three or fourprojections 10 spaced equally. about the rim are sufficient for lockingthe rim to the felly.

Figures 1 to 3 inclusive clearly show the locking plate 9 while Figures4 to 6 in elusive show one of the locking projections 10..

I will now define the specific construction of the rim locking plate 9.In Figure 2 it will be noted that the felly 1 is provided with adepression 11 which is adapted to receive a bolt 12. The bolt 12 isprovided with a non-circularhead13 and a non-circular nut 14. The boltand nut have coniv cal-shaped portions 15 and 16. The sides 17 and 18have conical-shaped openings 19 and 20 therein in which the conicalportions 15 and 16 are rotatably disposed. This constructioii permitsthe bolt 12to be rotated,

through which the bolt 12 extends. It will therefore be seen that whenthe bolt 12 is rotated, it will move the locking plate 9 with respect tothe telly 1. In Figures 1 and 3 I have shown the side 3 as beingprovided with an opening 23 through which the locking plate 9 is adaptedto slide. The side 2, however, is cut away as at 24, (see Figure 1) soas to permit the movement ot the locking plate 9 with respect to thetelly In the present torm ot the device the locking plate 9 isrectangular in shape and has two outwardly extending ribs 25 which areinclined with. respect to the axis of the bolt 12, (see Figure 1). Theribs 25 provide a channel 26 in which a projection 28 carried by the rim8, is adapted to be received.

The projection 28 is punched out ot the inner side otthe rim 8 and'isprovided with tapered sides 29, which permit the "projection to bereadily received in the channel The cam sides 29 are shaped so as topermit the rim to be formed by dies. The projection 28 is turned so asto have its side 30 disposed parallel with the inner wall of: one of theribs 25. It will also be noted that the projection 28 does not contactwith both ot the inner walls ot the ribs 25. This permits a movement ofthe locking plate with respect to the projection 28 tor a purposehereinatter described.

It will be noted that when the locking plate 9 is moved, it will movethe projection 28 laterally so as to move the rim 8 into lockingposition. This movement is positive, since the ribs engage with theprojection 28 and move the projection. It will be noted that the lockingplate 9 has the channel 26 thereof provided with an inclined portion 31.The inner side ot the projection 28 is moved into contact with theinclined portion 31 by a means hereinafter described, and when theprojection 28 so engages with the inclined portion it will be moved awayfrom the telly 1 so asto cause the rim to bind to the telly. IThcprojection 28 rotates the rim slightly with respect to the telly 1 butdoes not prevent lateral movement of the rim with respect to the telly.

The n'ieans tor preventing lateral movement ot the rim with respect tothe telly consistsot the PlOjCCilOHS 10 and camshaped portions 6 and 7ot the telly. Fig ure 4' showst-he projection 10 as being provided withan inclined surtacc 32. Figure 6 shows how-the beveled side 32 contactswith the inclined portion6 and Fig. 4 shows the portion 6 cont as beinginclined at The side 32 ot the projection 10 and the portion ot theinclined surtace (i coact with each other so as to cause the pr jection10 to be moved inwardly in the direction indicated by the arrow a andalso radially from the telly 1.

acted by the projection 10 so as to cause the rim to bind with thetelly. As heretofore stated, the projections are dis posed about the rimand therefore bind the rim to the telly at various points about thetelly so as to make a rigid connection be tween the rim and telly. Inaddition to the contacting ot the surtaces 32 and 33 the rim 8 alsobears against the inclined surface 7. It should be noted that thesurtace 7 contacts with the rim 8 throughout its entire circumference,thus providing a large sup porting area tor the rim. The movement ot theprojection 10 in the direction of the arrow (4 causes the portion 3a ofthe rim 8 to contact with the inclined surface 7 The inclined surtacecauses the rim to be moved slightly away trom the tellyso as to bind therim to the telly and prevent movement thereof with respect to the telly.

The valve of. the tire (not shown) is first inserted in the openingtherefor in the folly and then the rim is swung so as to dispose the rimon the telly. The projection 28 is disposed diametrically opposite tromthe valve so as to permit the rim to be readily applied to the telly;The projection 28 and the project-ions 10 are aligned with the channel26 and the recesses 37 respectively when the valve is inserted in theopening therefor in the telly. This permits the opera tor to swing therim into place. The opera tor then rotates the bolt 12 by means of awrench, whereupon the locking plate 9 will move the projection 28circumferential]y to cause the projectionslO to engage with the surface6 and thus wedge the rim to the telly. The rim and telly have beendesigned so as to consist of a number 0t inclined surfaces which engagewith each other so as to wedge the rim to the telly when the plate 9 ismoved.

W hen releasing the rim the bolt 12 is rotated in the opposite directionand causes the projection 28 to move the rim so as to align theprojections 10 with the recesses 37. As heretofore stated, the sides otthe projection 28 do not contact with both sides of the channel 26.There is therefore no tendency tor the projection to become locked inthe channel. In case the side 30 should adhere to the wall of the rib25, a slight tap upon the rim with a hammer or other tool will releasethe projection and permit the plate to move the projection. In this waythe rim may be readily released from the telly even though the rim hasbeen rigidly secured to the telly tor a long time.

The weight ot the rim with the tire on it is so great as to render themounting of: the rim on the telly quite ditlicnlt it it were necessaryto push the rim onto the telly and at the same time turn it to cause theusual wedging action which forces the rim into position, as set forth inmy above menvt-ioned application, But this weight becomes of greatassistance in the present case for the recesses formedby cutting awaythe flange 6 of the felly in order to admit the projections 10 permitthe free entrance of these projections.

lVhen the rim is lifted onto the wheel, and the tire tube valve stem isinserted in the properhole therefor in the felly in the usual manner,the rim and tire thereon may be swung away from the felly and thenviolently swung back against the felly. The projections 10 enter theirrecesses-withoutmeeting any obstructions but the projection 28 contactswith the inclined shoulder :25 (on the right side of the lock plate inFig. 1). As this look plate can be properly positioned by means of thebolt 12, this en gagement takes place just before the rim engagestherear flange on the felly at 7.

This forcible engagement of the projection 28 with the inclined shoulderforces the rim to slide around circumferentially on the felly to such anextent that the projections 10 will extend back of the inclinedshoulders 33 (Figs. 4- and 5). sutliciently to hold the rim in positionon the felly. It is then merely necessary to turn the bolt 12 to pullthe lock plate outward, which results in all the projections 10 ridingup on the inclined surfaces 33 and the rim being locked in position.

This initial kick causing the partial rotation of the tire following theslam of the rim against the felly is of great importance for thechanging of this rim is thereby rendered as simple and easy as that ofthe present demountable rim, If the rim were given no initial rotationto bring the pro jections 10 into operative position to hold the rim onthe felly, the inclined shoulder on the locking plate, when pulled outagainst the projections 28, would merely push the rim off the felly. Butwhen such movement is preventedby this operative engagement of theprojections 10, the rim is forced to slide around the felly. As only asingle locking bolt is necessary in the present construction, the timerequired to change rims is materially reduced and the cost ofconstruction correspondingly diminished.

The depression 11 permits the felly to use a rim which is of specialconstruction. The rim is shown in Figure 3 as being provided with asupporting surface 38 for the outer casing, and a supporting surface 39for the inner tube. In this type of rim, when the tire is deflated, theouter casing may be forced down into contact with the surfaces 39 andthereby permit the outer casing to bulge at one point so as to free theouter casing from the rim at this point, and allow it to be removed fromthe rim. It is obvious that the felly may support the standard rim withbut slight alterations. The arrangement of the contacting surfaces inthe rim and felly is such as to provide a device in which the rimwillbind with the fellyxeven though there is a slight imperfectioninsthe parts, and even after the rim and felly have become slightly wornthrough use. 4) are inrealit-y double cam surfaces, which not onlymovethe rim laterally with respect to the folly l but also radially.

In Figure 7 I have shown amodified form of the device which is identicalwith the preferred form except that it is adapted to be used with discwheels. In this Figure I have shown a disc wheel 40 which has a lockingplate actuating bolt 41 rotatably carried by the disc 40. The lockingplate 42 operates in the same manner as the plate 9 and locks the rim 8tothe disc wheel in the same manner as is done in the preferred form ofthe device. The disc wheel i0 is fashioned into a cylindrical portionl?) which is similar, to the cylindrical portion 1 (see Figure 6) and isalso provided with a cam-shaped surface l4: which is similar to thesurface 7 (see Figure 6). The operation of this form of the device isidentical to the preferred form and therefore needs no furtherdescription.
